LA PAZ – Bolivian prosecutors are investigating a dozen former senior police officers on suspicion of exploiting their posts for personal gain, media outlets said Wednesday.

The inquiry was promoted by the Transparency and Anti-Corruption Ministry, which detected irregularities in the officers’ financial disclosure statements.

Six of the officers under investigation are former provincial commanders, while the rest led specialized units, the official ABI news agency said, citing Transparency Minister Lenny Valdivia.

The minister said that starting in January, all high-ranking police and military officers will have to submit sworn asset declarations every year.

The requirement will be extended in 2017 to all police and armed forces personnel, including civilians.

Bolivia’s national police force is facing an institutional crisis after a series of arrests of senior officers accused of corruption.

President Evo Morales, whose administration has been frustrated in its efforts to reform the police, announced in June a program of rewards for rank-and-file cops who expose wrongdoing by their superiors.
